2. Description of Related Art

According to the trend of the modern society that has diversifiedrapidly, persons use cosmetics as needed regardless of sex and age. Inparticular, in the case of women, makeup is done using a variety ofcosmetics, makeup products having various colors and makeup tools.

In general, makeup is largely classified into basic makeup, color(cosmetic) makeup, hair makeup, and body makeup, in which the colormakeup has the purpose of decorating more beautifully after the basicmakeup is finished, so the color makeup is considered as a practicalmakeup that is performed by taking into account aesthetic, color, andfashionable senses.

Various types of color cosmetics are used for the above-described colormakeup, and the color cosmetics are largely classified into skinexpression cosmetics such as makeup base, foundation, and powder, eyecosmetics such as eye shadow, eye liner, eyebrow, and mascara. lipcosmetics such as lipstick, lip gloss, and lip cream, and cheek-touchcosmetics and the color cosmetics are manufactured in liquid or gelform, or solid or powder form and stored and used in cosmetic containersof various shapes depending on the characteristics thereof.

Accordingly, it has become necessary to develop containers for varioustypes of cosmetics depending on the purpose of use and characteristicsof the cosmetics. In general, liquid or gel cosmetics are filled in aglass container or tube container and used in a way that the user putsthe cosmetics on the hand or squeeze the cosmetics to apply thecosmetics onto the skin.

However, such a conventional cosmetic container has a problem in that itis inconvenient to use the cosmetic container and the cosmetic materialis wasted because the user has to put the cosmetics on the hands andthen wash the hands whenever the user uses the cosmetics.

In order to solve the above problems, a compact container with abuilt-in puff has been developed so that it is not necessary to get acosmetic material on the hand and it is easy to carry.

Such conventional compact containers are disclosed in Korean UtilityModel Registration No. 20-0157472 and Korean Utility Model RegistrationNo. 20-0458647. These related arts include a cosmetic dish in which thecosmetic is stored, a lower case in which the cosmetic dish is stored,an upper case for opening and closing the lower case, and a cosmeticpuff accommodated in the upper and lower cases.

However, since the conventional compact container has no structure inwhich the cosmetic dish for storing the cosmetic is separated from thelower case, it is impossible to separately refill and use the cosmeticdish when the cosmetic material is completely exhausted. Thus, there wasa problem that resources are wasted and the economic burden is increasedon users because the users need to repurchase the compact container.

Korean Patent Registration No. 10-1584512 discloses a compact containerfor solving such a problem. The conventional compact container includesan outer container, a refill container coupled to the inside of theouter container to receive cosmetic materials therein, a refill uppercontainer that opens and closes the refill container, and an upper outercontainer that opens and closes the outer container, in which the outercontainer and the refill container are undercut-coupled such that theouter container and the refill container can be attached to and detachedfrom each other. When the cosmetic material contained in the refillcontainer is used up, the refill container can be separated from theouter container, and a new refill container can be coupled to the outercontainer.

However, the conventional compact container has a structure in which theinner container storing the cosmetics is forcibly separated from theouter container by pushing the bottom portion of the inner containerexposed to the outside in order to replace the inner container from theouter container. As a result, it is difficult for a woman havingrelatively weak strength to separate the refill container from the outercontainer. In addition, when the inner container is pressed excessivelyby a hand, noise is generated when the inner container is separated fromthe outer container, and the inner container suddenly jumps up and fliesaway, which is inconvenient in replacement and use.

In the drawing ofthe cosmetic container according to an aspect of the present disclosure,the lower case 10 is illustrated as a cylindrical shape having a lowheight and a wide width, but the present disclosure is not limitedthereto, and the shape of the lower case may be changed variouslyaccording to convenience of use, preference of a purchaser or fashion.

As shown in FIG. 2, the lower case 10 may include a case body 20 and acontent case 30 coupled to the inside of the case body 20.

A button insertion hole 22 may be formed in one side of the case body20, and a button 24 may be installed in the button insertion hole 22, inwhich the button 24 is pressed by a user to fasten or release the lowercase 10 and the upper case 40 while moving back and forth. At least onesurface of the button 24 may be exposed to the outside of the case body20, and a first locking protrusion 24 a may protrude from an upperportion of the button 24 so as to be coupled with a second lockingprotrusion 44 of the upper case 40.

A connection block insertion groove 26 may be formed opposite to thebutton 24 of the case body 20, and the connection block 50 may beslidably inserted into a lower portion of the connection block insertiongroove 26. Separation prevention grooves 26 a may be recessed on bothside walls of the connection block insertion groove 26 so that theconnection block 50 does not come out from the case body 20 when theupper case 40 is rotated. Accordingly, it is possible to prevent theconnection block 50 from being unintentionally separated from the casebody 20. In this case, preferably, the connection block insertion groove26 may be configured to extend vertically along the height direction ofthe case body 20, and the separation prevention groove 26 a may be apair of grooves configured to extend vertically from both side walls ofthe connection block insertion groove 26.

As shown in FIG. 3, the content case 30 may include a bottom surface 31,an inner wall 32 extending upward from the bottom surface 31, anintermediate wall 33 spaced apart from the inner wall by a predetermineddistance and extending upward, and an outer wall 34 spaced apart fromthe intermediate wall 33 and extending upward, in which cosmeticcontents or an impregnation sponge S impregnated with the cosmeticcontents may be accommodated in an inner space surrounded by the bottomsurface 31 and the inner wall 32.

Meanwhile, a rim plate 36 may be formed on an upper end of the outerwall 34 of the content case 30 while extending horizontally outward. Therim plate 36 may cover an upper end of a rim of the case body 20 toprevent the inner space of the case body 20 from being exposed to theoutside and prevent external impurities from penetrating into the insideof the case body 20. As shown in FIG. 2, a button through hole 36 a maybe formed in one side of the rim plate 36 so that the first lockingprojection (24 a) of the button (24) may pass through the button throughhole 36 a, a first upper case insertion groove 36 b may be formedopposite to the button through hole 36 a so that a part of the uppercase 40, that is, an inner surface of the shaft coupling portion 36 maybe inserted into the first upper case insertion groove 36 b, and a firsthinge portion 36 c may protrude upward between the button through hole36 a and the first upper case insertion groove 36 b. In this case,preferably, the button through hole 36 a of the rim plate 36 may belocated adjacent to the button insertion hole 22 of the case body 20,and the first upper case insertion groove 36 b may be located adjacentto the connection block insertion groove 26 of the case body 20.

In addition, a first fastening portion 38, which is detachably coupledto the connection block 50 by magnetic force, may be formed at a lowerportion of the rim plate 36. The first fastening portion 38 may includea fastening section 38 a and a pair of insertion sections 38 b bent froman end of the fastening section 38 a. One surface of the fasteningsection 38 a may come into close contact with a lower surface of the rimplate 36 and may be exposed to the top of the connection block insertiongroove 26 so that the fastening section 38 a may be fastened to orseparated from the connection block 50, which is inserted into theconnection block insertion groove 26, and the insertion sections 38 bmay be bent from the end of the fastening section 38 a and inserted intothe case body 20. In addition, the first fastening section 38 may beseated on the upper end of the case body 20 and may be pressed and fixedby the rim plate 36 of the content case 30. In this case, the firstfastening portion 38 may be preferably formed of a metal plate such thatit can be attracted by magnetic force of a magnet.

In addition, a content case cover 60 for opening and closing the contentcase 30 may be further coupled to one side of the content case 30. Inthis case, the content case cover 60 may be formed in a disk shapehaving a predetermined diameter so as to completely cover the open upperportion of the content case 30. A handle 62 may protrude outward fromone side of the content case cover 60 so that the user can easily gripthe content case cover 60 and a second hinge portion 66 that ishinge-coupled to the first hinge portion 36 c formed on the content case30 may be formed on the location opposite to the handle 62. In addition,a sealing ring 64 may protrude downward from the lower portion of thecontent case cover 60 to make close contact with an inner circumferenceof the intermediate wall 34 of the content case 30, thereby sealing theinside of the content case 30 when the content case cover 60 is closed.

Meanwhile, the upper portion of the content case 30 may be furthercoupled with a ring-type fastener 70, which prevents the impregnationsponge S accommodated in the content case 30 from coming out of thecontent case 30. A part of the ring-type fastener 70 may be fixed to aninner wall 32 of the content case 30, and the remaining part may extendhorizontally toward the inside of the inner wall 32.

As described above, the lower case 10 may be assembled by combining thecase body 20 with the content case 30, and the rim plate 36 of thecontent case 30 may cover an upper portion of the block insertion groove26 of the case body 20, so that the connection block 50 inserted intothe connection block insertion groove 26 may be released downward of thecase body 20 without being released upward of the case body 20. That is,as shown in the partially enlarged view of FIG. 2, the connection blockinsertion groove 26 has a configuration in which lower and outerportions thereof are open, an upper portion thereof is closed, and theopen outer portion has a width relatively narrower than that of an innerportion thereof.

The upper case 40 may open or close the content case 30 of the lowercase 10 while rotating at a predetermined angle.

As shown in FIG. 3, a mirror 42 may be formed on the inner surface ofthe upper case 40 so that the user can make up while illuminating themakeup area, and a second locking projection 44 may be formed on theinner circumference of the upper case 40 so as to be engaged with thefirst locking protrusion 24 a of the case body 20.

In addition, a shaft coupling portion 46 may extend downward from thelocation opposite to the second locking protrusion 44 so as to beshaft-coupled to the connection block 50. The shaft coupling portion 46may include an extension portion 46 a extending vertically from an endof the upper case 40 and a coupling portion 46 b that is formed on anend of the extension portion 46 a and shaft-coupled to the connectionblock 50, in which an inner surface of the extension portion 46 a may beinserted into the first upper case insertion groove 36 b of the contentcase 30 and a second upper case insertion groove 57 of the connectionblock 50, and the coupling portion 46 b may be inserted into a shaftinsertion hole 52 of the connection block 50.

As shown in FIG. 1, the upper case 40 may be opened while rotating 180degrees or more from the lower case 10. In the cosmetic containeraccording to an aspect of the present disclosure, the upper case 40 andthe lower case 10 may be shaft-coupled through the connection block 50,in which the shaft coupling portion 46 extending downward of the uppercase 40 may be rotate in a state in which it is inserted into the shaftinsertion hole 52 of the connection block 50, thus, unlike theconventional existing open structure, the upper case 40 may behorizontally opened while being completely turned over withoutinterfering with the lower case 10.

The connection block 50 may be configured to connect the lower case 10and the upper case 40, and may be shaft-coupled to the upper case 40 anddetachably coupled to the lower case 10 by magnetic force. In this case,the connection block 50 may be connected to the inner side of the shaftcoupling portion 46 of the upper case 40, and slidably inserted into alower portion of the connection block insertion groove 26 of the lowercase 10.

As shown in FIG. 2, the shaft insertion hole 52 may be formed in thelower center of the connection block 50 so that the end of the shaftcoupling portion 46 of the upper case 40 may be inserted into the shaftinsertion hole 52. In this case, a hinge pin crossing the shaftinsertion hole 52 may be coupled to the inner portion of the shaftinsertion hole 52, and preferably, the shaft coupling portion 46 may behinge-coupled by the hinge pin. The shaft insertion hole 52 may providea shaft coupling space between the upper case 40 and the connectionblock 50 as well as a shaft rotation space for the shaft couplingportion 46. Accordingly, the shaft coupling portion 46 of the upper case40 may rotate naturally from the lower case 10 without being caught byother parts. Preferably, a portion of one surface of the connectionblock 50, which is exposed to the outside of the lower case 10, iscurved in accordance with the surface curvature of the lower case 10 forthe beauty or luxury of appearance of the cosmetic container and thecontinuity of the design.

In addition, an insertion groove 54 may be formed inside the center ofthe connection block 50, and a second fastening portion 58 may beinserted into the insertion groove 54. The insertion groove 54 may beformed adjacent to the rim plate 36 of the content case 30, and onesurface of the insertion groove 54 adjacent to the rim plate 36 may beopened. This is to allow the magnetic force to effectively act betweenthe first fastening portion 38 formed in the lower case 10 and thesecond fastening portion 58 formed in the connection block 50. In thiscase, preferably, the second fastening portion 58 may be formed of amagnet to attract the first fastening portion 38 by magnetic force. Inthe cosmetic container according to an aspect of the present disclosure,the first fastening portion 38 is described as a metal plate, and thesecond fastening portion 58 is described as a magnet, but the disclosureis not limited thereto. The first fastening portion 38 and the secondfastening portion 58 may be interchanged, or both the first fasteningportion 38 and the second fastening portion 58 may be formed of magnets.

Meanwhile, separation prevention protrusions 56 may protrude from bothsides of the connection block 50 so as to be engaged with the separationprevention grooves 26 a of the lower case 10. That is, the connectionblock 50 may be slidably inserted into the lower portion of theconnection block insertion groove 26 of the lower case 10, and at thesame time, the separation prevention protrusions 56 of the connectionblock 50 may be inserted into the connection block insertion groove 26of the lower case 10. Through the above dove-tail structure (which is afitting type of the slide surface and refers to a structure in which aprotrusion like a pigeon tail is engaged with a corresponding groove),the connection block 50 may slide only vertically without being releasedto the lateral side of the lower case 10. Accordingly, in a state inwhich the shaft coupling portion 46 of the upper case 40 and theconnection block 50 are connected in a straight line, the connectionblock 50 may be separated from or fastened to the lower case 10 bypulling downward or pushing upward the connection block 50. In thiscase, both surfaces of the connection block 50 and the surface of theseparation prevention protrusion 56 may serve as sliding surfaces thatmake contact with the connection block insertion groove 26 of the lowercase 10.

In addition, the second upper case insertion groove 57 may be formed onone surface of the connection block 50, which is exposed to the outsideof the lower case 10, so that the inner surface of the shaft couplingportion 46 of the upper case 40 may be inserted into the second uppercase insertion groove 57.

As described above, in the cosmetic container according to an aspect ofthe present disclosure, the upper case 40 is rotatably shaft-coupled tothe connection block 50, and the connection block 50 is coupled to thelower case 10 such that the connection block 50 can be naturallyfastened to or separated from the lower case 10 by magnetic force,thereby facilitating the replacement of the lower case 10 and improvingthe convenience of use. In addition, the connection block 50 can beslidably inserted from the bottom of the lower case 10 and fitted withthe lower case 10 in a dove-tail structure, so that the upper case 40,which is shaft-coupled to the connection block 50, can stably rotatewithout be rattled or shaken and cannot be easily separated from thelower case 10 when opened or closed.
